Thundercloud Plum (Prunus cerasifera 'Thundercloud') Pollination Information

The Thundercloud Plum (Prunus cerasifera 'Thundercloud') is a self-fertile fruit tree, meaning that it is capable of producing fruit without the need for cross-pollination with another tree of the same species. However, cross-pollination with another plum tree or a compatible apricot tree may increase the yield and quality of the fruit.

To ensure the best pollination, it is recommended to plant at least two or more compatible pollinating trees within 50 feet of each other. Some suitable pollinators for the Thundercloud Plum include the Santa Rosa Plum (Prunus salicina 'Santa Rosa'), the Burgundy Plum (Prunus salicina 'Burgundy'), and the Moorpark Apricot (Prunus armeniaca 'Moorpark').

Pollination occurs when bees or other pollinators transfer pollen from the male parts of the flower (anthers) to the female parts (stigma) of the same or a compatible tree. It is important to make sure that the pollinators are active during the blooming period of the Thundercloud Plum, which typically occurs in late winter to early spring.

In addition to natural pollination, manual pollination can also be done by hand using a soft-bristled brush or cotton swab to transfer pollen from one flower to another. This can be helpful if pollinators are scarce or if there are few compatible trees in the area.
